I've got a full clear bra on the hood, fenders and bumpers. The hood is in three pieces, a large piece covering the majority of the hood and two small pieces covering the corners near the windshield. Mirrors are partials.
I'd suggest the 3M material. I just had hood redone because of an inferior product that lost its sheen after about two years as a daily driver. The original installer chose to do the hood only with a different material for some reason.
Be sure to search your regional forum for recomendations for a high quality installer in your area and check out their work. Details matter in the end. The folks who did my hood (Detailing Dynamics) wrapped the edges with the material. In my opinion this is far superior look to cutting it flush with the edge of the panel because the material shinks slightly in time.
As a side note, it was great to see the hood looking good as new when the old bra was removed. Well worth the cost. I'll see if I can take some pictures tomorrow.
